You’d think a Dodge Challenger Demon would leave a Jeep Grand Cherokee Trackhawk in the dust at top speed on an empty airstrip, but Jason Fenske at Engineering Explained thinks otherwise and here’s why.
On paper the Dodge Demon is a fiend, powered by a Supercharged 6.2L Hemi SRT Demon V8 engine delivering 840 hp and 770 lb-ft of torque, it has a manufacturer claimed quarter mile time of just 9.65 seconds. While still impressive, the Trackhawk’s 6.2-liter supercharged engine lags behind with 707 hp and 645 lb-ft of torque. But the Demon tops out at 168 mph while the Trackhawk is capped 180 mph.
Of course in a short drag race, the Demon’s hard launch will help it pull ahead, but eventually the Jeep will catch up once the Demon tops out. That’s because the drag radial tires are rated for that amount and Dodge electronically limited the Demon to a maximum speed of just 168 mph. Theoretically, if you were to get an appropriate set of racing tires and remove the limiter, the Demon could hit speeds of around 200 mph.
On the other hand, the Trackhawk sit on some 295’s with a higher speed rating. It could probably go faster if the body was more aerodynamic.
